Just curious because I have not been to any but what are the chances of finding a DE razor in an antique store?
Chances are good, but the razors condition is another question. Search ebay too. I'm actually surprised at how much NOS (new old stock) there is out there still, even stuff as old as 60 years old. From time to time someone will stumble upon an old cache of discarded or auctioned-off government/military emergency supply kits that contained brand new never used Gillette Tech razors or similar.
There was a NOS 66 (I think)Tech from canada and a NOS Krona but the price was to high for me. I didn't have the funds for the tech either. Not big on ebay , but I do appreciate the input.
